Eltech engineers is one of the leading manufacturers and suppliers of premium quality and precision engineered machinery that includes corona treatment systems, corona treatment equipment, static eliminators, induction cap sealing machines, ozone generators and static chargers.

The water-based and uv inks printed on plastic films and other substrates create a need for the substrate to be treated prior to printing. Corona treating is a very effective way to increase the adhesion of virtually any plastic material. Corona treatment increases the surface tension of the sheet or fabrics receptive to inks by inducing molecular changes in the surface of the films or sheets.

Corona treatment system increases the surface treatment that is required for plastic films or fabrics whose normal surface tension is not sufficiently high to permit good wetting by flexo graphic inks. Conventional method of roll to roll treatment is standard practice, corona treatment is required to increase surface tension or improve the printability in the offset sheet. Some substrates are corona-treated when they are manufactured. Many of these Substrates require a surface energy boost to match a particular ink or coating. This is done With corona pretreaters on the press just prior to the coating application point.

Pvc, pp, ld, foam, flex, metallised polyester, pe, opp, and other high-low density Plastic materials should particularly be corona treated to enhance the quality of the final Product.
